BACKGROUND/AIMS: Various non-invasive tools (NITs) predicting first hepatic decompensation (HD) in advanced chronic liver disease (ACLD) enclose platelet (PLT) count. A relevant proportion of metabolic dysfunction-associated steatotic liver disease (MASLD)-ACLD patients do not show splenomegaly- and hypersplenism-related thrombocytopenia. We aimed to evaluate the performance of NITs in predicting HD according to ultrasound-assessed spleen size.
METHODS
In this observational study, 148 splenic and 27 asplenic (ASP) MASLD-compensated advanced chronic liver disease (cACLD) patients were enrolled. Ultrasound artificial intelligence-based tools distinguished splenomegaly-affected patients (SAPs) and normal-spleen patients (NSPs). Albumin-Bilirubin score (ALBI) and PLT count-based NITs (PLNs) (Fbrosis-4 [FIB-4], ALBI-FIB-4, red cell distribution width-to-PLT ratio [RPR], liver stiffness measurement [LSM]-to-platelet ratio [LSM/PLTr], and ANTICIPATE ± non-alcoholic steatohepatitis [NASH]) were determined. Over 3 years, the first HD was recorded.
RESULTS
Limitedly to SAP, spleen area inversely correlated with PLT (relationship [R]: -0.981; < 0.0001), confirming the role of splenomegaly-related hypersplenism in conditioning thrombocytopenia. HD occurred similarly in SAPs (20.48%), NSPs (21.15%), and ASP patients (25%) (: 0.198). In NSP, PLNs showed a reduced influence on HD (FIB-4 [: 0.03], ALBI-FIB-4 [: 0.001], RPR [: 0.002], LSM/PLTr [: 0.01], and ANTICIPATE ± NASH [: 0.001]) compared to SAP. In NSP, the spleen area was inversely associated (adjusted sub-distribution hazard ratio: 0.870) and more significantly ( < 0.0001) impacted HD. Consistently, unlike SAPs, in NSPs and ASP patients, PLNs showed poor performance, and exclusively ALBI maintained a good accuracy (NSP: area under the curve [AUC]: 0.651, : 0.04; ASP patients: AUC: 0.625, : 0.03) in predicting 3-year HD.
CONCLUSION
Ultrasound-assessed spleen size affects the predictive performance of the PLNs in MASLD-cACLD patients.
背景/目的：各种预测晚期慢性肝病（ACLD）首次肝失代偿（HD）的非侵入性工具（NITs）包括血小板（PLT）计数。相当一部分代谢功能障碍相关脂肪性肝病（MASLD）-ACLD患者未表现出脾肿大和脾功能亢进相关的血小板减少。我们旨在根据超声评估的脾脏大小评估NITs预测HD的性能。
方法
在这项观察性研究中，纳入了148例有脾的和27例无脾（ASP）的MASLD代偿期晚期慢性肝病（cACLD）患者。基于超声人工智能的工具区分了脾肿大影响的患者（SAPs）和脾脏正常的患者（NSPs）。测定了白蛋白-胆红素评分（ALBI）和基于PLT计数的NITs（PLNs）（纤维化-4 [FIB-4]、ALBI-FIB-4、红细胞分布宽度与PLT比值[RPR]、肝脏硬度测量值[LSM]与血小板比值[LSM/PLTr]以及ANTICIPATE ± 非酒精性脂肪性肝炎[NASH]）。在3年多的时间里，记录首次HD情况。
结果
仅在SAP中，脾面积与PLT呈负相关（相关性[R]：-0.981；P<0.0001），证实了脾肿大相关的脾功能亢进在导致血小板减少中的作用。HD在SAP患者（20.48%）、NSP患者（21.15%）和ASP患者（25%）中的发生率相似（P=0.198）。在NSP中，与SAP相比，PLNs对HD的影响降低（FIB-4 [P=0.03]、ALBI-FIB-4 [P=0.001]、RPR [P=0.002]、LSM/PLTr [P=0.01]以及ANTICIPATE ± NASH [P=0.001]）。在NSP中，脾面积与HD呈负相关（调整后的亚分布风险比：0.870）且影响更显著（P<0.0001）。同样，与SAP不同，在NSP和ASP患者中，PLNs表现不佳，只有ALBI在预测3年HD时保持了良好的准确性（NSP：曲线下面积[AUC]：0.651，P=0.04；ASP患者：AUC：0.625，P=0.03）。
结论
超声评估的脾脏大小影响PLNs在MASLD-cACLD患者中的预测性能。
